Karun Chandhok is to make his Chandhok will replace Jarno Trulli for the German Grand Prix, with the race his first since being ousted by Hispania Racing midway through last season.
The Indian driver competed in 10 grands prix during Hispania's maiden campaign prior to stepping aside and eventually being taken on as a test and reserve driver at Lotus.
Team principal Tony Fernandes has confirmed Chandhok's promotion is a one-off event for now as they are committed to re-signing Trulli for next year.
Fernandes, however, feels it is incumbent on his team to give the likes of Chandhok an opportunity.
"Ever since I first met Karun I have been impressed with his whole demeanour - he is talented, passionate, committed and he brings great energy to the whole team," said Fernandes.
"I am delighted we are giving him the chance to add even more value to us in the cockpit over a whole race weekend.
"For Formula One to continue to develop globally we need to keep creating new opportunities for talent from around the world to reach the top, and Team Lotus will continue to do its best to support that."
With regard to veteran Italian Trulli, Fernandes added: "He has been extremely accommodating in stepping to the side for this race and our commitment to him is unwavering.
"I am delighted to confirm we are in the process of negotiating an extension to his contract with us and we are all looking forward to unveiling the details of that very soon.
"He is a key member of our team and I hope we can give him a car as soon as possible that allows him to utilise his considerable talent to the full."
Chandhok, who has driven in four Friday morning practice sessions this season, knows there is pressure on him to now perform.
"Ever since I first joined the team I have been looking forward to this opportunity and I am determined to do my best to repay their faith in me and help the team progress, this season and for many years to come," said Chandhok.
"I am approaching the weekend in a very realistic frame of mind, but whatever happens, I am very excited about lining up on the grid on Sunday.
"I know there will be millions of Indian fans, and Team Lotus fans around the world, who will be behind me and the whole team, so I will do the best I can to give them something to cheer for."
